TRAFFIC HANDLING CAPABILITY OF A BROAD-BAND INDOOR WIRELESS NETWORK USING CDMA MULTIPLE-ACCESS

CDMA (code division multiple access) may be an attractive technique fo r wireless access to broadband services because of its multiple access simplicity and other appealing features. In order to investigate traf fic handling capabilities of a future network providing a variety of i ntegrated services, this paper presents a study of a broadband indoor wireless network supporting high-speed traffic using CDMA multiple acc ess. The results are obtained through the simulation of an indoor envi ronment and the traffic capabilities of the wireless access to broadba nd 155.5 MHz ATM-SONET networks using the mm-wave band. A distributed system architecture is employed and the system performance is measured in terms of call blocking probability and dropping probability, The i mpacts of the base station density, traffic load, average holding time , and variable traffic sources on the system performance are examined. The improvement of system performance by implementing various techniq ues such as handoff, admission control, power control and sectorizatio n are also investigated.
